.MKV to .MP4 (or .MOV) for AppleTV

[RevMayhem]

I'm trying to convert some DVDs I ripped to h264 to work with AppleTV without re-encoding. The source is h264 w/ 5.1 AC3 in .MKV. I use mkvextract v2.1.0 to extract the .h264 and .ac3 file. Then I use BeSweet+BeLight+Nero AAC DLLs to convert the audio to 5.1 AAC LC. I put it all back together using mp4box v0.4.5-DEV+YAMBv2.0.0.8. The resulting .MP4 file plays but using Quicktime 7.5 on a dual core PC or dual core MacBookPro it only plays back at around 14FPS. The source .MKV plays fine using VLC or any other player. I played around with the -inter options on mp4box but that didn't seem to help at all.

Any ideas?

mp4box command line:

"c:\yamb-2.0.0.8_20080121\mp4box.exe" -add "C:\TestMovie.h264:fps=23.976" -add "C:\TestMovi_Track1.mp4#1" -chap "C:\TestMovie_Chapters.txt" -frag 40 -v -new "C:\TestMovie-h264.mp4"

It seems your QT 7.5 does not like High-Definition H264 video.

Tried play with vlc or mplayer?

[RevMayhem]

Yep, you are right. It plays fine in Window Media Player. I'm still stumped. The source .MKV plays fine in VLC and Windows Media Player and so does the resulting .MP4. It just doesn't play at full speed in the latest version of Quicktime which is supposed to handle h264 up to 1280x720. I guess I need to find out if the bitrate is too high or if it's an issue with the the content.
